BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 shows constituent parts of a trowel with an adjuster according to an embodiment of the present invention. FIG. 1 (a) shows a front view, side view and rear view of an L angle, and FIG. 1 (b) shows a scale adjuster angle. A front view and a side view are shown, and a bolt, a nut, and a washer are shown in FIG. The L-angle 10 has an upright portion 11 extending in the vertical direction and a horizontal portion 12 that is bent at a substantially right angle from the upright portion 11, and the lower surface of the horizontal portion 12 can be used as a trowel surface. The upright portion 11 is formed with a pair of circular screw holes 13. A scale 14 is displayed on the back surface of the upright portion 11, and here, scales of parallel lines indicating 2 mm, 3 mm, 5 mm, and 10 mm are carved in order from the top.

The scale adjuster angle 20 has an upright portion 21 extending in the vertical direction and a horizontal portion 22 that can be bent at a right angle from the upright portion 21 and can be used as a trowel surface. The upright portion 21 has a vertical direction. A pair of elongated holes 23 for adjusters extending in parallel with each other are formed. The outer shape of the scale adjuster angle 20 is the same as the L angle 10, and when the upright portions 11 and 21 of both angles are made to meet each other, the position of the slot 23 corresponds to the position of the screw hole 13.

In this embodiment, the L angle 10 and the scale adjuster angle 20 each have a width of 5
The height of the screw hole 13 is 0 mm and the height is 25 mm. The screw hole 13 has a diameter of 4 mm at a position 8 mm inward from the side of the upright portion 11. Similarly, the elongated hole 23 for the adjuster has the upright portion 21.
4 mm wide and 15 mm long 8 mm from the side of The L angle 10 and the scale adjuster angle 20 are preferably made of an aluminum alloy, and the surfaces thereof are anodized to improve the wear resistance. The alumite plating thickness is about 40 microns to increase strength. Other than the above, the angle may be formed using, for example, stainless steel.

The L angle 10 and the scale adjuster angle 20 are fixed with a pair of bolts 31 and nuts 32. The bolt 31 is made of brass,
The shaft has a diameter of 4 mm in accordance with the screw hole 13. The diameter of the head of the bolt 31 is approximately 10 mm. It is preferable that the surfaces of the bolt 31 and the nut 32 are plated with chrome. A washer may be used on the bolt side and / or the nut side when fastening with the bolt 31.

FIG. 2 shows a trowel 1 in which an L angle 10 and a scale adjuster angle 20 are assembled. Trowel 1
The L angle 10 and the scale adjuster angle 20 are fixed by a bolt 31. Screw hole 13 of L angle 10 and scale adjuster angle 20
Both angles are fixed by positioning the long hole 23 and the bolt 31 through the screw hole 13 and the long hole 23 and fastening the nut 32. Since the scale adjuster angle 20 has a pair of elongated holes 23 extending in the vertical direction, the scale adjuster angle 20 can be moved in the vertical direction relative to the L angle 10 by utilizing the elongated holes 23. That is, the horizontal portion 22 of the scale adjuster angle 20 can be assembled so as to have an offset (step) with respect to the horizontal portion 12 of the L angle 10, and the offset amount D
Can be freely adjusted within the range of the length of the long hole 23.

In this embodiment, a scale 14 is provided on the back surface of the L angle 10 so that the offset amount D can be easily determined. Set the horizontal part 22 of the scale adjuster angle 20 to the L angle 10
When offsetting from the horizontal portion 12, the top portion 24 of the scale adjuster angle 20 indicates the scale of the scale 14 according to the offset amount D. For example, if you want to set the offset amount D to 3 mm, set the scale adjuster angle 20 to L angle 1
Slide from 0 and scale adjuster angle 2
The top 24 of 0 may be aligned with the parallel line on the second 3 mm scale from the top, and then fixed by the bolt 31.
Alternatively, when it is desired to set the offset amount D to 5 mm, the scale adjuster angle 20 may be further slid so that the top 24 of the scale adjuster angle 20 is aligned with the parallel line of the 5 mm scale, and the bolt 31 may be used for fixing. Although the scale 14 shows only the offset amount D up to 10 mm scale, when the scale adjuster angle 20 is maximally offset from the L angle 10, that is, when the top of the slot 23 is brought into contact with the bolt 31. The offset amount D is set to be 15 mm.
In this way, each trowel surface of the trowel 1 with an adjuster can be easily offset by a required step, and since the scales of the scale 14 are parallel lines, the parallel tops 24 of the scale adjuster angles 20 are parallel lines. The trowel surface can be made parallel just by matching.

Next, a construction method using the iron with an adjuster according to the present embodiment will be described. As shown in FIG. 3A, after the concrete skeleton 41 has been cast, the wooden frame 42 is removed from the concrete skeleton 41, and grooves 43 are formed on the surface thereof. At this time, the roughness of the surface of the concrete skeleton 41 is about ± 5 mm.

Next, as shown in FIG. 2B, leveling is performed so that the parting piece 44 made of stainless steel or the like is horizontal in the groove 43, and in the groove 43, the gap between the concrete frame 41 and the parting piece 44 is mortar. Fill with 45. At this time, a step P is formed between the top surface of the parting piece 44 and the surface of the concrete skeleton 41.

Next, as shown in FIG. 1C, a premix mortar 46 is applied, and the surface of the concrete skeleton is finished using the trowel 1. Offset amount D of trowel 1
Is determined according to the thickness of the member finally processed on the premix mortar 46. For example, if the final processed material has a thickness of 5 mm, the offset amount of the trowel 1 is set to 5 mm so that the step difference between the parting material 44 and the premix mortar 46 is set to 5 mm. Adjust the thickness. When finishing the step including the parting metal fitting 44, the lower surface of the horizontal portion 12 of the L angle 20 of the iron 1 is
It moves so as to follow the top surface of the parting metal object 44, and at the same time, the lower surface of the horizontal portion 22 of the scale adjuster angle 20 acts as a trowel surface, and the surface of the premix mortar 46 is ±
Finish with a roughness accuracy within 0.5 mm. Conventionally,
I had no choice but to rely on the skill of the plasterer, but by using the trowel 1 with such an offset trowel surface, it is possible to easily finish the stepped portion and further offset the trowel surface. By making the amount D adjustable, it is possible to adapt to various required steps. The surface roughness accuracy of the premix mortar 46 determines the flatness of the floor surface, and the step difference from the parting piece 44 determines the flatness between the final processed product and the parting piece 44.
In each case, the accuracy is important.

FIG. 5D shows a state where the final processed material 47 is applied on the premix mortar 46, and an example in which a carpet tile having a thickness of 5 mm is applied as the final processed material on the left side A surface, On the B side on the right side, 2 as the final processed material
An example in which a P tile having a thickness of millimeter is applied will be shown. As described above, by using the trowel 1 according to the present invention, it is possible to perform the step finish of the premix mortar 46 very easily and easily, so that the carpet tile 47a and the P tile 47b become flat with the cut metal article 44. It can be installed on.
In particular, it is also very convenient when forming barrier-free floors for which demand is increasing.

Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications are possible within the scope of the gist of the present invention described in the claims. Can be modified and changed. For example, the offset amount D of the trowel 1 is not limited to the example of the above-described embodiment, and can be appropriately changed according to the purpose. It goes without saying that the material, shape, size, etc. of the iron can be changed as appropriate. Further, the construction using the trowel is not necessarily limited to the construction of a concrete floor surface having a step, but can be applied to a skeleton having a step such as a wall or a beam.
